Fix Anaconda + Jupyter Notebook 'module not found' errors (make Jupyter work with multiple Pythons!)

Did you install Anaconda but Jupyter Notebook can’t find Anaconda? Or you run Jupyter but nothing seems to be installed? It’s a kernel problem! Let’s walk through how to solve “module not found” errors when Jupyter can’t find the Python you want to use.

Commands:
conda activate base
python -m ipykernel install --user --name anaconda-base --display-name "Anaconda (base)"

Alternatively, if you want to install another kernel from pyenv (or any other kind of python) you'll run two commands, one to install the connect-to-Jupyter-through-a-kernel package and one to actually install the Python kernel:
~/.pyenv/versions/3.8.2/bin/python -m pip install ipykernel
~/.pyenv/versions/3.8.2/bin/python -m ipykernel install --user --name pyenv-382 --display-name “3.8.2 (pyenv)”

Not sure where all of your pythons are? Use "which -a python" to list all pythons in your PATH. Not all of these commands work on Windows, but the ipykernel ones will.

Thank you for not just solving the issue but by explaining the paths! it really helped me to wrap my head around Jupyter environments and where they are pulling from.

I am grateful for this video. After doing everything right and not able to initiate the work was so much frustrating. Very easy to go through this video though I work on windows. Thank you so much sir Jonathan.

Good, this tutorial solved my problem of installing a desktop jupyter-lab and the python environment became mismatch.

Thank you so much! I have been researching everywhere to solve the problem. I am glad to find your video!

Anyone know how I would do this on a Windows machine? Which command is not recognized.

[MetaMaths]

I am trying to use a python library (not Conda) . I install it with pip but the Jupiter notebook says 'no module found'. What can I do in this case ?

My English skill is not good, but I can fix this problem.

!which -a python if i write in jupyter notebook it shows "which" is not recognized as internal or external command, operable program or batch file.

[KVarunTejaRA]

excellent short and clear video man
keep it up tq

[kacper]

Thanks for tutorial! It works pretty well.

"!which" doesn't work: "'which' is not recognized as an internal or external command, operable program or batch file."

[ThatGuy-zwle]

i did all that, got the kernel option to show like in 11:05. I picked the base and i still can't import conda. I'm dead inside.

[svitirur]

i will like to install jupyter notebook in different directory how

[anupdholam]

This is in Linux environment . Do we have something for windows
